Compare the Top 10 Best IP PBX Software of 2021

TOP 10 IP PBX Software for 2021

Before we jump to describing the top 10 IP PBX solutions for 2021 let’s travel back in time to 2013 when Marty Parker published an article on forecasting the demise of PBX or IP PBX. No, this was not a sweeping generalization but referenced to voice only communications, mentioning UC in the same breath. Yes, 8 years later, IP PBX software has evolved and is thriving even as platforms such as Asterisk and Freeswitch allow for greater and smoother integration of wide-ranging codecs and protocols as well as API integrations to smooth the UC experience. From another perspective you would expect WebRTC to make inroads into IP PBX but that is not the case; on the contrary, IP PBX now integrates WebRTC for seamless audio-video calls and conferences plus document exchange. Now, let us take a look at few IP PBX solutions, not necessarily the best, top 10 IP PBX software for 2021 and not in any particular order.


  1.  HoduPBX – IP PBX Software
